Benzyltriethylammonium Tetrathiomolybdate

[146785-42-4] C26H44N2S4Mo (MW 608.85) InChI = 1S/2C13H22N.Mo.4S/c2*1-4-14(5-2,6-3)12-13-10-8-7-9-11-13;;;;;/h2*7-11H,4-6,12H2,1-3H3;;;;;/q2*+1;;;;2*-1 InChIKey = BVXREDYYTDDNGI-UHFFFAOYSA-N (used as a sulfur transfer reagent and for a variety of reductive transformations) Physical Data: mp −150 °C (dec.). Solubility: soluble in CH3CN, DMF, and DMSO; sparingly soluble in CH2Cl2 and CHCl3. Form Supplied in: brick red crystals, available as ammonium tetrathiomolybdate. Preparative Methods: a solution of benzyltriethylammonium chloride (23.3 g, 102.5 mmol) in distilled water (60 ml) was added to a rapidly stirred solution of ammonium tetrathiomolybdate (13 g, 50 mmol) in distilled water (60 ml). Rapid stirring was continued for 2 h at room temperature and the solid that separated was filtered and washed with isopropyl alcohol (40 ml) and ether (40 ml). After drying under high vacuum, red crystals of benzyltriethylammonium tetrathiomolybdate (1) (24 g, 80%) were obtained in pure form. Handling, Storage, and Precautions: stored in nitrogen atmosphere, decomposes on prolonged exposure to air. Incompatible with strong acids and oxidizing agents.
